When components of a steel structure are identified with this ASTM designation, but the product form is not listed in the scope of this specification, the material shall conform to one of the standards listed below unless otherwise specified by the purchaser.

Table abridged to show only those items relevant to Ramesh Steel Corporation

This is not to say that the materials listed above conform to or can be made from A36 steel, simply that if the purchaser calls out a product per A36, but one that is not covered in the above scope (shapes, bars, plates), the manufacturer or supplier can supply product conforming to the above standards. For example, anchor bolts called out as A36 would be supplied as F1554 Grade 36.
